Radio interferometric data often suffer from the presence of RFI in frequency channels. RFI is sudden unwanted bright radio signals from different terrestrial sources. They are usually localized in frequency, affecting a few frequency channels. Radio astronomical observations are usually taken with high time and frequency resolution [1]}, which helps identify RFI contamination and subsequently flag the affected timestamps/frequency channels. This introduces irregular visibility samples, which introduces spurious structures in the data. While performing Fourier transforms for calculating PS, these irregularities introduce oscillatory structures in the PS domain. Since the target signal is weak, this can adversely affect the data recovery[2]}.
